BUSINESS OF EAST WISCONSIN SAVINGS BANK

General

Organized in 1887, the Bank is a Wisconsin-chartered stock savings bank that operates through its headquarters in Kaukauna and branches in Appleton, Freedom, and Kimberly, Wisconsin.

Our business consists primarily of taking deposits from the general public and investing those deposits, together with funds generated from operations, primarily in one- to four-family residential real estate loans, as well as marine and recreational vehicle loans, home equity loans and lines of credit, and other consumer loans. To a lesser extent, we originate commercial real estate, multifamily, construction and commercial loans. At December 31, 2025, $129.7 million, or 68.0%, of our total loan portfolio was comprised of one- to four-family residential real estate loans, $30.2 million, or 15.9%, of our total loan portfolio was comprised of marine and recreational vehicle loans, $12.2 million, or 6.4% of our total loan portfolio was comprised of construction loans, $8.9 million, or 4.6%, of our total loan portfolio was comprised of home equity loans and lines of credit, $3.5 million, or 1.8% of our total loan portfolio was comprised of commercial loans, $3.2 million, or 1.7%, of our total loan portfolio was comprised of other consumer loans and $3.0 million, or 1.6% of our total loan portfolio was comprised of multi-family and commercial real estate loans. We also invest in securities, consisting primarily of U.S. Treasury and federal agency securities, including agency mortgage-backed securities, securities issued by state and political subdivisions and corporate bonds. We offer a variety of deposit accounts, including certificates of deposit, money market accounts, savings accounts and interest-bearing and noninterest-bearing demand accounts. We historically have utilized advances from the Federal Home Loan Bank to assist in funding our operations and we had $38.4 million of FHLB advances at December 31, 2025.

The Bank is subject to comprehensive regulation and examination by the Department and the FDIC. Our website address is www.eastwis.com. Information on our website is not considered a part of this document.

Market Area

We conduct our operations from our headquarters and three branch offices, all of which are located in Outagamie County, Wisconsin. We consider our primary lending market area to be Outagamie County, Wisconsin, and its adjoining counties.

The economy in our primary market area has benefited from being varied and diverse, with a broad economic base with underlying support from the presence of diverse manufacturing and medical technology institutions.

Competition

We face competition within our market area both in making loans and attracting deposits. Our market area has a concentration of financial institutions that include large money center and regional banks, community banks and credit unions. We also face competition from savings institutions, mortgage banking firms, consumer finance companies, financial technology or “fintech” companies and credit unions and, with respect to deposits, from money market funds, brokerage firms, mutual funds and insurance companies. Based on FDIC data at June 30, 2025 (the latest date for which information is available), we had 5.2% of the FDIC-insured deposit market share in Outagamie County, making us the eighth largest out of 19 banks operating in the county.

We expect competition to increase in the future as a result of legislative, regulatory and technological changes and the continuing trend toward consolidation of the financial services industry. Technological advances, for example, have lowered barriers to entry, which have allowed banks to expand their geographic reach by providing services over the internet and made it possible for non-depository institutions, including financial technology companies, to offer products and services that traditionally have been provided by banks. Competition for deposits and the origination of loans could limit our growth in the future.

Lending Activities

Our principal lending activity is originating one- to four-family residential real estate loans, as well as marine and recreational vehicle loans, construction, home equity loans and lines of credit, and other consumer loans. To a lesser extent, we originate commercial real estate, multifamily, and commercial loans. Subject to market conditions and our asset-liability analysis, we expect to continue to grow our originations of one- to four-family residential real estate loans (both owner-occupied and non-owner occupied) and, to a limited degree, marine and recreational vehicle loans and commercial real estate loans. We currently sell a significant majority of the longer term, fixed-rate one- to four-family residential real estate loans that we originate on a servicing retained basis while retaining shorter term fixed-rate, and adjustable-rate one- to four-family residential real estate loans in order to manage the duration and time to repricing of our loan portfolio.

Loan Portfolio Composition. The following table sets forth the composition of our loan portfolio by type of loan at the dates indicated. We had no loans held for sale, at December 31, 2025 or December 31, 2024.

One- to Four-Family Residential Real Estate Lending. The primary focuses of our lending has long been the origination of long-term loans secured by mortgages on primarily owner-occupied, one- to four-family residences. At December 31, 2025, $129.7 million, or 68.0%, of our total loan portfolio, consisted of one- to four-family residential real estate loans. The vast majority of the one- to four-family residential real estate loans that we originate are secured by properties located in our primary market area. See “Originations, Sales and Purchases of Loans.” At December 31, 2025, $13.6 million, or 11.9% of residential mortgage loans, were secured by non-owner occupied properties. At December 31, 2025, our largest residential mortgage loan had an outstanding balance of $1.3 million and was performing according to its original terms. The average principal loan balance of our one- to four-family residential real estate loans was $147,851 at December 31, 2025.

Our one- to four-family residential real estate loans are generally underwritten to secondary market guidelines. We currently sell a significant majority of the fixed-rate one- to four-family residential real estate loans that we originate on a servicing retained basis while retaining shorter term fixed-rate and adjustable-rate one- to four-family residential real estate loans in order to manage the duration and time to repricing of our loan portfolio. See “Originations, Sales and Purchases of Loans.” We generally limit the loan-to-value ratios of our one- to four-family residential real estate loans to 80% of the appraised value, purchase price or cost, whichever is lowest. In addition, we may make one- to four-family residential real estate loans with loan-to-value ratios in excess of 80% of the appraised value, purchase price or cost, whichever is less, where the borrower obtains private mortgage insurance. We also originate certain non-conforming loans in excess of limits established by the Federal Housing Finance Agency, which are referred to as “jumbo loans.” We generally underwrite jumbo loans in a manner similar to conforming loans and at December 31, 2025, approximately 1.6% of our one- to four-family residential real estate loans were jumbo loans with an average balance of less than $540,000.

Our fixed- and adjustable-rate one- to four-family residential real estate loans are originated with terms of up to 30 years, though one- to four-family residential real estate loans often remain outstanding for shorter periods than their contractual terms because borrowers have the right to refinance or prepay their loans. At December 31, 2025, $75.6 million, or 46.7%, of our one- to four-family residential real estate loans were adjustable-rate loans.

We originate our adjustable-rate one- to four-family residential real estate loans with initial fixed interest rate periods of three, five and seven years and then adjust annually for the balance of the loan term, based on changes in a designated market index. Generally, these loans are limited to a 100 basis point (1%) initial increase/decrease in their interest rate, a 100 basis point (1%) increase/decrease in their interest rate annually after the initial adjustment and a maximum upward adjustment of 600 basis points (6%) over the life of the loan and the floor being the designated interest rate margin (2.75% minimum). We determine whether a borrower qualifies for an adjustable-rate mortgage loan based on our lending policy.

A subset of our one to four-family residential real estate operation is our construction lending, primarily to owner occupied consumer borrowers. At December 31, 2025, we had $12.2 million in construction loans. Our construction loans are primarily secured by properties in our market area. Our construction loans are fixed-rate interest-only loans that provide for the payment of interest during construction phase. At the end of the construction phase, the loan may convert to a permanent mortgage loan or may be paid in full. These loans are underwritten to our normal residential real estate underwriting procedures. At December 31, 2025, or largest outstanding construction loan was for $1.7 million of which $1.2 million was outstanding. The loan was performing according to its contractual terms at December 31, 2025.

We generally do not offer “interest-only” mortgage loans on one- to four-family residential real estate loans, except with regard to our construction loans, as described above. We do not offer loans that provide for negative amortization of principal, such as “Option ARM” loans, where the borrower can pay less than the interest owed on their loan, resulting in an increased principal balance during the life of the loan. Additionally, we do not offer “subprime loans” (loans that are made with low down-payments to borrowers with weakened credit histories typically characterized by payment delinquencies, previous charge-offs, judgments, bankruptcies, or borrowers with questionable repayment capacity as evidenced by low credit scores or high debt-burden ratios).

We evaluate both the borrower’s ability to make principal, interest and escrow payments and the value of the property that will secure the loan. Our one- to four-family residential real estate loans do not currently include prepayment penalties, are non-assumable and do not produce negative amortization. Our one- to four-family residential mortgage loans customarily include “due-on-sale” clauses giving us the right to declare the loan immediately due and payable in the event that, among other things, the borrower sells the property subject to the mortgage. All borrowers are required to obtain title insurance or an attorney’s opinion. We also require homeowner’s insurance and fire and casualty insurance and, where circumstances warrant, flood insurance on properties securing real estate loans.

Marine and Recreational Vehicle Lending. At December 31, 2025, we had $30.2 million, or 15.9%, of our total loans in marine and recreational vehicle loans. Marine and recreational vehicle loans are typically made through a long-standing broker relationship and are primarily secured by boats and motor homes purchased in the upper Midwest of the United States. These loans typically have a maximum loan term of 15 years and are made at a fixed rate. For each marine or recreational vehicle loan arranged through our broker relationship, we generally pay the broker a commission based on the size of the loan. Marine and recreational vehicle loans are generally limited to no more than 120% of invoice for new and 100% of National Automobile Dealers Association Marine Appraisal Guide used price plus taxes and fees. Marine and recreational vehicle borrowers generally have very high credit scores, substantial down payments, substantial net worth, personal liquidity, and excess cash flow. Marine and recreational vehicle lending supports our ALCO management as such loans generally have shorter terms and higher rates than fixed-rate residential loans.

Home Equity Loans and Lines of Credit. In addition to one- to four-family residential real estate loans, we offer home equity loans and lines of credit that are secured by the borrower’s primary or secondary residence. At December 31, 2025, we had $8.9 million, or 4.6%, of our total loan portfolio in home equity loans and lines of credit.

Home equity loans and lines of credit are generally underwritten using the same criteria that we use to underwrite one- to four-family residential real estate loans with terms of up to 15 years. Home equity loans and lines of credit may be underwritten with a loan-to-value ratio of up to 90% when combined with the principal balance of the existing first mortgage loan.

Home equity loans and lines of credit are generally secured by junior mortgages and have greater risk than one- to four-family residential real estate loans secured by first mortgages. We face the risk that the collateral will be insufficient to compensate us for loan losses and costs of foreclosure, after repayment of the senior mortgages, if applicable. When customers default on their loans, we attempt to foreclose on the property and resell the property as soon as possible to minimize foreclosure and carrying costs. However, the value of the collateral may not be sufficient to compensate us for the amount of the unpaid loan and we may be unsuccessful in recovering the remaining balance from those customers. Particularly with respect to our home equity loans and lines of credit, decreases in real estate values could adversely affect our ability to fully recover the loan balance in the event of a default.

Other Consumer Loans. We originate limited amounts of other consumer loans. At December 31, 2025, our portfolio of other consumer loans totaled $3.2 million, or 1.7% of our total loan portfolio. The other consumer loans that we originate generally consist of loans secured by automobiles, deposits and miscellaneous other types of installment loans including a limited amount of unsecured personal loans.

Commercial. At December 31, 2025, commercial loans were $3.5 million, or 1.8% of total loans. Our commercial loans include both term loans and lines of credit made with either fixed or adjustable interest rates. Almost the entire portfolio is comprised of loans originated and serviced by a national broker specializing in the professional and healthcare industries. All loans purchased are fully reviewed and underwritten pursuant to our policies and procedures.

Multifamily Lending and Other Commercial Real Estate. Our commercial real estate and multifamily loans are secured primarily by owner-occupied commercial properties, multifamily properties and retail or mixed use properties, almost all of which are located in our Outagamie County lending market and the surrounding area. At December 31, 2025, we had $3.0 million in the aggregate in multifamily loans and other commercial real estate, representing 1.6% of our total loan portfolio.

We generally originate adjustable-rate multifamily and other commercial real estate loans with maximum terms of up to 30 years. From time to time, we will also originate fixed-rate loans in these portfolios. We generally limit loan-to-value ratios to 95% of the appraised value or purchase price, whichever is lower. Loans over 80% are required to have mortgage insurance. All of our multifamily and other commercial real estate loans are subject to our underwriting procedures and guidelines.

At December 31, 2025, neither our largest multifamily loans-to-one borrower nor our largest other commercial real estate loans-to-one borrower was at or exceeding $1.6 million.

We consider a number of factors in originating multifamily and other commercial real estate loans. We evaluate the qualifications and financial condition of the borrower (including credit history), profitability and expertise, as well as the value and condition of the mortgaged property securing the loan. When evaluating the qualifications of the borrower, we consider the financial resources of the borrower, the borrower’s experience in owning or managing similar property and the borrower’s payment history with us and other financial institutions. In evaluating the property securing the loan, among other factors we consider the net operating income of the mortgaged property before debt service and depreciation, the debt service coverage ratio (the ratio of net operating income to debt service) to ensure that, subject to certain exceptions, it is at least 1.20x for multifamily and other commercial real estate loans. Our multifamily and other commercial real estate loans are appraised by outside independent and qualified appraisers that are duly approved in accordance with the Bank’s policy. Personal guarantees are often obtained from multifamily and other commercial real estate borrowers. Each borrower’s financial information on such loans is monitored on an ongoing basis by requiring periodic financial statement updates.

Loan Underwriting Risks

Adjustable-Rate Residential Real Estate Loans. Although adjustable-rate mortgage loans may reduce to an extent our vulnerability to changes in market interest rates because they periodically reprice, as interest rates increase, the required payments due from the borrower also increase (subject to rate caps), increasing the potential for default by the borrower. At the same time, the marketability of the underlying collateral may be adversely affected by higher interest rates. Upward adjustments of the contractual interest rate are also limited by the maximum periodic and lifetime rate adjustments permitted by our loan documents.

Construction. Our construction loans are based upon estimates of costs and values associated with the completed project. Underwriting is focused on the borrower’s financial strength, credit history and demonstrated ability to produce a quality product and effectively market and manage their operations.

Construction lending involves additional risks when compared with permanent lending because funds are advanced upon the security of the project, which is of uncertain value prior to its completion. Risk of loss on a construction loan also depends on the accuracy of the initial estimate of the value of the property at completion of construction compared to the estimated cost (including interest) of construction and other assumptions. Because of the uncertainties inherent in estimating construction costs, as well as the market value of the completed project and the effects of governmental regulation on real property, it is relatively difficult to evaluate accurately the total funds required to complete a project and the related loan-to-value ratio. In addition, generally during the term of a construction loan, interest may be funded by the borrower or disbursed from an interest reserve set aside from the loan budget. If the estimate of construction cost is inaccurate, we may be required to advance additional funds beyond the amount originally committed in order to protect the value of the property. Moreover, if the estimated value of the completed project is inaccurate, the borrower may hold a property with a value that is insufficient to assure full repayment of the loan upon the sale of the property. Construction loans also carry the risk that construction will not be completed on time in accordance with specifications and projected costs. These loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project and the ability of the borrower to sell or lease the property or obtain permanent take-out financing, rather than the ability of the borrower or guarantor to repay principal and interest. If the appraised value of a completed project proves to be overstated, we may have inadequate security for the repayment of the loan upon completion of construction of the project and may incur a loss in the event of non-payment by the borrower.

Marine and Recreational Vehicle Lending. Marine and recreational vehicle loans may entail greater risk than one- to four-family residential real estate loans. Repossessed collateral for a defaulted marine or recreational vehicle loan may not provide an adequate source of repayment for the outstanding loan and a small remaining deficiency often does not warrant further substantial collection efforts against the borrower. Further, any collateral securing such loan will likely depreciate over time, be difficult to appraise and fluctuate in value.

Consumer Loans. Consumer loans may entail greater risk than residential mortgage loans, particularly in the case of consumer loans that are unsecured or secured by assets that depreciate rapidly, or for which there is a limited re-sale market. Repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment for the outstanding loan and a small remaining deficiency often does not warrant further substantial collection efforts against the borrower. Consumer loan collections depend on the borrower’s continuing financial stability and therefore are likely to be adversely affected by various factors, including job loss, divorce, illness or personal bankruptcy. Furthermore, the application of various federal and state laws, including federal and state bankruptcy and insolvency laws, may limit the amount that can be recovered on such loans.

Multifamily and Other Commercial Real Estate Loans. Loans secured by multifamily properties or other commercial real estate generally have larger balances and involve a greater degree of risk than owner-occupied, one- to four-family residential real estate loans. The primary concern in commercial real estate lending is the borrower’s creditworthiness and the feasibility and cash flow potential of the project. Payments on loans secured by income properties often depend on successful operation and management of the properties. As a result, repayment of such loans may be subject, to a greater extent than residential real estate loans, to adverse conditions in the real estate market or the economy. To monitor cash flows on income properties, we may require borrowers and loan guarantors to provide quarterly, semi-annual or annual financial statements, depending on the size of the loan, on commercial real estate loans. In reaching a decision on whether to make a commercial real estate loan, we consider and review a global cash flow analysis of the borrower and consider the net operating income of the property, the borrower’s expertise, credit history and profitability and the value of the underlying property. We have generally required that the properties securing these real estate loans have an aggregate debt service ratio, including the guarantor’s cash flows and the borrower’s other projects, of at least 1.20x for multifamily and commercial real estate loans. While this is a small percentage of our business, our analysis may require an environmental phase one report when the possibility exists that hazardous materials may have existed on the site, or the site may have been impacted by adjoining properties that handled hazardous materials.

If we foreclose on a multifamily or commercial real estate loan, the marketing and liquidation period to convert the real estate asset to cash can be lengthy with substantial holding costs. In addition, vacancies, deferred maintenance, repairs and market stigma can result in prospective buyers expecting sale price concessions to offset their real or perceived economic losses for the time it takes them to return the property to profitability. Depending on the individual circumstances, initial charge-offs and subsequent losses on commercial real estate loans can be unpredictable and substantial. As of December 31, 2025, we held no “other real estate owned” as a result of foreclosures (or the acceptance of a deed in lieu of foreclosure).

Commercial. Unlike residential real estate loans, which generally are made on the basis of the borrower’s ability to make repayment from his or her employment or other income, and which are secured by real property whose value tends to be more easily ascertainable, commercial loans are of higher risk and typically are made on the basis of the borrower’s ability to make repayment from the cash flows of the borrower’s business. As a result, the Bank historically has had a very small presence in this space. Such loans must comply with our consumer lending guidelines. Commercial loans are primarily loans purchased from a national financial services firm that specializes in loans to the professional and healthcare industries. Like consumer loans, the commercial loans that we purchase from this firm may entail greater risk than residential mortgage loans. Like consumer loans, collections on commercial loans depend on the borrower’s continuing financial stability, and therefore are likely to be adversely affected by various factors, including job loss, divorce, illness or personal bankruptcy.

Credit support provided by the borrower for most of these loans is based on the enforcement of a personal guarantee. Further, any collateral securing such loans may depreciate over time, may be difficult to appraise and may

fluctuate in value. As a result, the availability of funds for the repayment of commercial loans may depend substantially on the success of the business itself.

Originations, Participations, Sales and Purchases of Loans

Our loan originations are generated by our loan personnel operating at our banking offices and mortgage loan originators. Additionally, in recent years, we have purchased consumer and commercial loans. We also obtain referrals from existing and former customers and from accountants, real estate brokers, builders and attorneys. All loans we originate are underwritten pursuant to our policies and procedures which incorporate secondary market underwriting guidelines to the extent applicable for residential loans.

While we originate both fixed-rate and adjustable-rate loans, our ability to generate each type of loan depends upon relative borrower demand and the pricing levels as set in the local marketplace by competing banks, thrifts, credit unions, and mortgage banking companies. Our volume of real estate loan originations is influenced significantly by market interest rates, and, accordingly, the volume of our real estate loan originations can vary from period to period.

Consistent with our interest rate risk strategy, we originate for sale and sell a significant majority of the longer term, fixed-rate one- to four-family residential real estate loans that we originate on a servicing retained basis while retaining shorter term fixed-rate, adjustable-rate and non-conforming one- to four-family residential real estate loans in order to manage the duration and time to repricing of our loan portfolio. We consider our balance sheet as well as market conditions on an ongoing basis in making decisions as to whether to hold loans we originate for investment or to sell such loans, choosing the strategy that is most advantageous to us from a profitability and risk management standpoint.

In addition, we have sold loans to the FHLB pursuant to the Mortgage Partnership Finance program consisting of long-term, fixed-rate single-family residential loans originated which have interest rates below certain levels established by the board of directors. Such sales provide for a limited amount of recourse. At December 31, 2025, the outstanding balance of our loans subject to recourse was approximately $34.4 million with a remaining credit obligation balance of approximately $993,000.

As a supplement to our in-house loan originations, we have entered into an agreement with an unaffiliated broker as a source for certain marine and recreational vehicle loans. This broker does not have an ownership interest in or any common employees or directors. The broker is located in our market area. For each marine or recreational vehicle loan arranged through our broker relationship, we generally pay the broker a commission based on the loan amount. We use the same parameters in evaluating these loans as we do for our in-house loan originations.

We also have an agreement with a national financial services firm that specializes in loans to the professional and healthcare industries. The Bank purchases loans originated by this firm as they offer unique features designed to provide a reliable source of quality loan portfolio growth that is fully compliant with our lending guidelines. The firm services these loans and the Bank holds the notes. These loan purchases can only be approved by an officer of the Bank and are limited, in aggregate, to 20% of total capital. Loans purchased from the firm are fully documented and reviewed for multiple factors, including, but not limited to, debt-to-income, cash flow coverage, FICO and other matrix scores, and all the loans have terms of 180 months or less.

We occasionally purchase loan participations in commercial loans originated by another local financial institution acting as the lead lender. In these circumstances, we follow our customary loan underwriting and approval policies. At December 31, 2025, the outstanding balances of our loan participations where we are not the lead lender totaled $2.5 million, or 1.31% of our loan portfolio. All such loans were performing in accordance with their original repayment terms. Historically, we have not purchased whole loans.

Loan Approval Procedures, Loans to One Borrower Limit and Lending Authority

Pursuant to applicable Wisconsin law, the aggregate amount of loans that we are permitted to make to any one borrower or a group of related borrowers is generally limited to 20% of our capital (25% if the amount in excess of 20%

is secured by “readily marketable collateral”). At December 31, 2025, based on the 20% limitation, our loans-to-one-borrower limit was approximately $3.7 million.

At December 31, 2025, our general internal limit on an aggregate loan relationship-to-one borrower (and related entities) was also 20% of our capital. At December 31, 2025, our largest loan relationship with one borrower was 6 loans aggregating to $1.9 million, which were secured by apartment buildings with four or less units that are located in Outagamie County. All of the loans were performing in accordance with their contractual terms on that date.

As a result of the offering, our loans-to-one borrower limit increased on a dollar basis and, consistent with our strategy to grow segments of our loan portfolio, we may originate and retain in our portfolio larger loan relationships, while also remaining diversified with smaller and mid-sized relationships as well.

Our lending is subject to written underwriting standards and origination procedures. Decisions on loans are made consistent with our loan policies and procedures, and the underwriting and review of a loan decision is designed primarily to determine the borrower’s ability to repay the requested loan.

The board of directors has overall responsibility for our lending policy, and the board reviews this policy at least annually.

The board of directors has delegated loan approval authority to certain officers up to prescribed limits, depending on the officer’s experience, the type of loan and whether the loan is secured or unsecured.

Delinquencies and Non-Performing Assets

Delinquency Procedures. When a borrower fails to make required payments on a loan, we take a number of steps to induce the borrower to cure the delinquency and restore the loan to current status. Past due notices are generated automatically once a loan is 16 days past due. If the payment is not received by the 30th day, a second notice is mailed. Collection activity including phone calls and other approved forms of communication may occur to remedy the delinquency. If the loan reaches 45 days past due without cooperation, a right to cure is sent out and the borrower has 15 days in which to satisfy the right to cure. If there are still no payments, and no cooperation on the part of the borrower, a demand letter is sent and we may consult with our attorney demanding that the loan be brought entirely current within 30 days. If there are still no payments and no cooperation from the borrower, the matter may be turned over to the attorney to start legal action for foreclosure when the loan reaches 120 days delinquent.

Loans Past Due and Non-Performing Assets. Loans are reviewed on a regular basis. Management determines that a loan is non-performing when it is probable at least a portion of the loan will not be collected in accordance with the original terms due to a deterioration in the financial condition of the borrower or the value of the underlying collateral has deteriorated if the loan is collateral dependent. When a loan is specifically identified as collateral dependent, the measurement of the loan in the allowance for credit losses is based on present value of expected future cash flows, except that all collateral-dependent loans are measured for impairment based on the fair value of the collateral. Non-accrual loans are loans for which collectability is questionable and, therefore, interest on such loans will no longer be recognized on an accrual basis. All loans that become 90 days or more delinquent are placed on non-accrual status unless the loan is well secured and in the process of collection. When loans are placed on non-accrual status, unpaid accrued interest is fully reversed, and further income is recognized only to the extent received on a cash basis. Generally, loans are restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time and the ultimate collectability of the total contractual principal and interest is no longer in doubt.

When we acquire real estate as a result of foreclosure, the real estate is classified as real estate owned. The real estate owned is recorded at the lower of carrying amount or fair value, less estimated costs to sell. Soon after acquisition, we order a new appraisal to determine the current market value of the property. Any excess of the recorded value of the loan satisfied over the market value of the property is charged against the allowance for credit losses, or, if the existing allowance is inadequate, charged to expense of the current period. After acquisition, all costs incurred in maintaining the

property are expensed. Costs relating to the development and improvement of the property, however, are capitalized to the extent of estimated fair value less estimated costs to sell. At December 31, 2025, we had no real estate owned.

We may modify the contractual terms of a loan to a borrower experiencing financial difficulties as a way to mitigate loss, proactively work with borrowers in financial difficulty, or to comply with regulations regarding the treatment of certain bankruptcy filing and discharge situations. A borrower is considered to be experiencing financial difficulty when there is significant doubt about the borrower’s ability to make required payments on the debt or to get equivalent financing from another creditor at a market rate for similar debt. A loan placed on nonaccrual because the borrower is experiencing financial difficulty may be returned to accrual status when all contractually due interest and principal has been paid and the borrower demonstrates the financial capacity to continue to pay as agreed, with the risk of loss diminished. We had no loans classified as modifications to borrowers experiencing financial difficulty as of December 31, 2025 and December 31, 2024.

Non-Performing Assets. The following table sets forth information regarding our non-performing assets. Non-performing assets include loans that are 90 or more days past due or on non-accrual status and real estate and other loan collateral acquired through foreclosure and repossession. Additionally, whenever management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, management may place such loans on non-accrual status immediately, rather than waiting until the loan become 90 days past due.

Classified Assets. Federal regulations provide that each insured savings institution classify its assets on a regular basis. In addition, in connection with examination of insured depository institutions, federal and Wisconsin

banking regulators have authority to identify problem assets and, if appropriate, classify them. There are three classifications for problem assets: “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss reserve is not warranted. Assets which do not currently expose the insured institution to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated as “special mention” by our management.

In connection with the filing of our periodic regulatory reports and according to our classification of assets policy, we regularly review the problem loans in our portfolio to determine whether any loans require classification according to applicable regulations. If a problem loan deteriorates in asset quality, the classification is changed to “substandard,” “doubtful” or “loss” depending on the circumstances and the evaluation. Generally, loans 90 days or more past due are placed on nonaccrual status and classified “substandard.”

The table below sets forth our classified loans at the dates indicated. We did not have any “special mention” loans at the dates indicated.

Other Loans of Concern. At December 31, 2025 there were no other loans of concern for which we had information about possible credit problems of borrowers that caused us to have serious doubts about the ability of the borrowers to comply with present loan repayment terms and that may result in disclosure of such loans in the future.

Provision for Credit Losses. We maintain an allowance for credit losses (“ACL”) at a level we believe is adequate to absorb estimated credit losses that are expected to occur within the existing loan portfolio through their contractual terms in accordance with applicable accounting standards. The level of the ACL is inherently subjective and is influenced by various factors, many of which are beyond our control, including, but not limited to, the performance of the loan portfolio, consideration of current economic trends, changes in interest rates and property values, estimated losses on pools of homogeneous loans based on an analysis that uses historical loss experience for prior periods that are determined to have like characteristics with management’s economic forecast period, such as pre-recessionary, recessionary, or recovery periods, portfolio growth and concentration risk, management and staffing changes, the interpretation of loan risk classifications by regulatory authorities and other credit market factors.

Our allowance for credit losses was $1.1 million at December 31, 2025 compared to $1.1 million at December 31, 2024. The ratio of our allowance for credit losses to total loans was 0.60% at December 31, 2025 and 0.60% at December 31, 2024, while the allowance for credit losses to non-performing loans is 378.5% on December 31, 2025 and considered to be insignificant and not measurable at December 31, 2024.

Additions to the allowance for credit losses are provided by charges against income based on various factors, which, in our judgment, deserve current recognition in estimating expected losses. Credit losses are charged-off in the period the loans, or portion thereof, are deemed uncollectible. Generally, the Company will record a loan charge-off (including a partial charge-off) to reduce a loan to the estimated fair value of the underlying collateral, less cost to sell, for collateral dependent loans. We regularly review the loan portfolio in order to maintain the allowance for credit losses in accordance with U.S. GAAP.

As an integral part of their examination process, the Department and the FDIC will periodically review our allowance for credit losses, and as a result of such reviews, we may determine to adjust our allowance for credit losses. However, regulatory agencies are not directly involved in the process for establishing the allowance for credit losses as the process is our responsibility and any increase or decrease in the allowance is the responsibility of management.

Investment Activities

General. Our investment policy is established by the board of directors. As part of the enhancement to our asset-liability, interest rate risk, and liquidity management process, in 2024, the board and management reviewed our investment portfolio composition and strategy and enhanced the investment policy with increased board oversight and reporting and addressed the perceived shortcomings in the former policy, including the immediate and long-term risk associated with the Bank’s previous investment strategy. The objectives of the enhanced policy are to: (i) provide and maintain liquidity within the guidelines of Wisconsin and federal banking laws and regulations, and to allow us to alter our liquidity position to meet both day-to-day and long-term changes in assets and liabilities; (ii) maintain high quality investments to minimize risk; (iii) provide collateral for pledging requirements; (iv); serve as a countercyclical balance to earnings and (v) maximize return on our investments.

Our investment policy is reviewed annually by our board of directors and all policy changes recommended by management must be approved by the board. Our president appoints an investment manager who administers and implements our investment policy and as such is authorized to manage our daily cash flows and make transfers from depositories to approved short-term investment accounts and invest in approved longer term investments based on our investment strategy to meet future funding needs or as a prudent utilization of excess liquidity. Any long-term investment must be reviewed by the board. The investment manager must request prior approval from the president or our Asset Liability Committee for any deviation from the investment policy.

We have legal authority to invest in various types of liquid assets, including U.S. Treasury obligations, securities of various government-sponsored enterprises and municipal governments, deposits at the FHLB, certificates of deposit of federally insured depository institutions and investment grade corporate bonds. We also are required to maintain an investment in FHLB stock. Derivative investments are not approved activities under the policy unless first studied and approved by the board.

At December 31, 2025 we had $58.7 million of investment securities (both held-to-maturity and available-for-sale), representing 21.7% of our total assets, and our investment portfolio consisted primarily of U.S. Treasury and federal agency securities, government-sponsored residential mortgage-backed securities (which includes collateralized

mortgage obligations) and corporate bonds. In addition, at December 31, 2025, we owned $2.8 million of FHLB stock. As a member of the FHLB, we are required to purchase stock in the FHLB, which stock is carried at cost and classified as restricted equity securities.

As of December 31, 2025, a portion of our investment portfolio was classified as held-to-maturity. These securities are carried at amortized cost net of any remaining unrealized gains or losses on them at the time the securities were classified as held-to-maturity. The following table sets forth the maturities and weighted average yields of these debt securities not carried at fair value through earnings as of December 31, 2025.

Sources of Funds

General. Deposits are our primary source of funds for use in lending and investment activities. We also use borrowings to supplement cash flow needs, to lengthen the maturities of liabilities for interest rate risk purposes and to manage the cost of funds. In addition, we receive funds from scheduled loan payments, investment maturities, loan prepayments, retained earnings and income on earning assets. While scheduled loan payments and income on earning assets are relatively stable sources of funds, deposit inflows and outflows can vary widely and are influenced by prevailing interest rates, market conditions and levels of competition. Our inability to generate core deposits may cause us to rely more heavily on wholesale funding strategies for funding and liquidity needs, which could have an adverse effect on our net interest margin and profitability.

Time with other financial institutions. At December 31, 2025, we had $4.5 million in time deposits with other financial institutions. Of this amount, $3.5 million will mature in 2026 providing an additional source of on balance sheet liquidity during the upcoming year.

Deposits. Our deposits are generated primarily from our primary market area. We offer a selection of deposit accounts, including noninterest-bearing and interest-bearing demand accounts, money market accounts, savings accounts and certificates of deposit. Deposit account terms vary, with the principal differences being the minimum balance required, the amount of time the funds must remain on deposit and the interest rate. We have the authority to accept brokered deposits but do not hold such deposits at December 31, 2025.

On a periodic basis, we establish interest rates paid, maturity terms, service fees and withdrawal penalties. Deposit rates and terms are based primarily on current operating strategies and market rates, liquidity requirements, rates paid by competitors and growth goals. We rely upon personalized customer service, long-standing relationships with customers, and the favorable image of the Bank in the community to attract and retain local deposits. We also seek to obtain deposits from our commercial loan customers.

The flow of deposits is influenced significantly by general economic conditions, changes in money market and other prevailing interest rates and competition. The variety of deposit accounts offered allows us to be competitive in obtaining funds and responding to changes in consumer demand. Based on experience, we believe that our deposits are relatively stable. However, the ability to attract and maintain deposits and the rates paid on these deposits, has been and will continue to be significantly affected by market conditions.

As of December 31, 2025 and December 31, 2024, the aggregate amount of total uninsured deposits (deposits in amounts greater than or equal to $250,000, which is the maximum amount for federal deposit insurance) was $32.5 million and $37.4 million, respectively. In addition, uninsured certificates of deposit totaled $17.9 million and $18.8 million as of December 31, 2025 and December 31, 2024, respectively. We have no deposits that are uninsured for any reason other than being in excess of the maximum amount for federal deposit insurance.

Borrowing Capacity. As a member of the FHLB, the Bank is eligible to obtain advances upon the security of the FHLB common stock owned and certain residential mortgage loans, provided certain standards related to creditworthiness have been met. FHLB advances are available pursuant to several credit programs, each of which has its own interest rate and range of maturities. At December 31, 2025, we had the ability to borrow an additional $26.9 million from the FHLB, subject to certain collateral requirements and had advances of $38.4 million at such date.

Additionally, at December 31, 2025 we had a $25.0 million available line of credit with the Discount Window at the Federal Reserve Bank of Chicago. In addition, at December 31, 2025 we had an unsecured $6.0 million federal funds line of credit with a correspondent bank. We have not drawn against the Discount Window or the federal funds line of credit.

Personnel and Human Capital Resources

Our success as a financial institution in our market areas is dependent on a workforce that embrace and are dedicated to our mission and culture. To continue to deliver on our mission and maintain our culture, it is crucial that we attract and retain talent who desire and have the experience to provide creative and innovative financial solutions and options for the diverse communities we serve. Through our hiring and retention programs we aim to create an inclusive workforce with diversified backgrounds and experiences. We strive to maintain a safe and healthy workplace, with opportunities for our employees to grow and develop in their careers, supported by advantageous compensation, benefits, health, and welfare programs.

As part of our compensation philosophy, we offer market competitive total rewards programs for our employees to attract and retain superior talent. These programs, include annual bonus opportunities, an Employee Stock

Ownership Plan, a matched 401(k) Plan, healthcare and insurance benefits paid time off, family leave, and flexible work schedules.

We encourage and support the growth and development of our employees and, wherever possible, seek to fill positions by promotion and transfer from within the organization. Additionally, all our employees are expected to display and encourage honest, ethical, and respectful conduct in the workplace. Our employees must adhere to our Code of Business Conduct and Ethics that sets standards for appropriate behavior and includes periodic training on preventing, identifying, reporting, and stopping discrimination of any kind.

Continual learning and career development is advanced through ongoing performance and development conversations with employees, internally developed training programs, customized corporate training engagements and other training events employees attend in connection with their job duties.

Employee retention helps us operate efficiently and achieve our business objectives. We believe actively prioritizing concern for our employees’ well-being, supporting our employees’ career goals, offering competitive wages and providing valuable fringe benefits aids in retention of our top-performing employees. At December 31, 2025, 65% of our current staff had been with us for five years or more.

As of December 31, 2025, we had 39 full-time employees and 1 part-time employee. We believe our relationship with our employees to be generally good. None of these employees are represented by a collective bargaining agreement.

The safety, health and wellness of our employees is a top priority. We promote the health and wellness of our employees by strongly encouraging work-life balance, offering flexible work schedules, keeping the employee portion of health care premiums to a minimum and sponsoring various wellness programs.

SUPERVISION AND REGULATION

General

The Bank is a stock savings bank organized under the laws of the State of Wisconsin. The lending, investment, and other business operations of the Bank are governed by Wisconsin law and regulations, as well as applicable federal law and regulations, and the Bank is prohibited from engaging in any operations not authorized by such laws and regulations. The Bank is subject to extensive regulation, supervision and examination by the Department and by the FDIC. This regulation and supervision establishes a comprehensive framework of activities in which an institution may engage and is intended primarily for the protection of the FDIC’s Deposit Insurance Fund and depositors, and not for the protection of security holders. As a registered bank holding company, EWSB Bancorp is regulated by the Federal Reserve Board. The Bank also is a member of and owns stock in the FHLB Chicago, which is one of the 11 regional banks in the Federal Home Loan Bank System.

Under this system of regulation, the regulatory authorities have extensive discretion in connection with their supervisory, enforcement, rulemaking and examination activities and policies, including rules or policies that: establish minimum capital levels; restrict the timing and amount of dividend payments; govern the classification of assets; provide oversight for the adequacy of loan loss reserves for regulatory purposes and the adequacy of its risk management framework; and establish the timing and amounts of assessments and fees imposed by the regulatory agencies. Moreover, as part of their examination authority, the banking regulators assign numerical ratings to banks relating to capital, asset quality, management, liquidity, earnings and other factors. These ratings rely on the supervisor’s judgment and the receipt of a less than satisfactory rating in one or more categories may result in supervisory action by the banking regulators against a financial institution. A less than satisfactory rating may also prevent a financial institution, such as the Bank or EWSB Bancorp, from obtaining necessary regulatory approvals to access the capital markets, pay dividends, acquire other financial institutions or establish new branches.

In addition, the Bank must comply with significant laws and regulations related to anti-money laundering and combating the financing of terrorism, Community Reinvestment Act (“CRA”), and fair lending. Government agencies have the authority to impose monetary penalties and other sanctions on institutions that fail to comply with these laws and regulations, which could significantly affect our business activities, including our ability to acquire other financial institutions or expand our branch network.

EWSB Bancorp is a registered bank holding company and is required to comply with the Bank Holding Company Act of 1956, as amended (“BHCA”), and the rules and regulations of the Federal Reserve Board. EWSB Bancorp is required to file certain reports with the Federal Reserve Board and is subject to examination by and the enforcement authority of the Federal Reserve Board. Additionally, the Federal Reserve Board also has supervisory authority for non-bank subsidiaries of bank holding companies. EWSB Bancorp is also subject to the rules and regulations of the SEC under the federal securities laws.

Any change in applicable laws or regulations, whether by the Wisconsin legislature, the Department, the Consumer Financial Protection Bureau, the FDIC, the Federal Reserve Board, the SEC or Congress, could have a material adverse impact on the operations and financial performance of EWSB Bancorp and the Bank.

Set forth below is a brief description of material regulatory requirements that are applicable to the Bank and EWSB Bancorp. The description is limited to certain material aspects of the statutes and regulations addressed, and is not intended to be a complete description of such statutes and regulations and their effects on the Bank and EWSB Bancorp.

Intrastate and Interstate Merger and Branching Activities

Wisconsin Law and Regulation. Any Wisconsin savings bank meeting certain requirements may, upon approval of the Department, establish one or more branch offices in the state of Wisconsin and the states of Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, and Ohio. In addition, upon Department approval, a Wisconsin savings bank may establish a branch office in any other state as the result of a merger or consolidation.

Federal Law and Regulation. The Interstate Banking Act permits the federal banking agencies to, under certain circumstances, approve merger transactions between banks located in different states, regardless of whether an acquisition would be prohibited under state law. The Interstate Banking Act, as amended, authorizes de novo branching into another state at locations at which banks chartered by the host state could establish a branch. The establishment of branches and bank mergers require the prior approval of the FDIC.

Loans and Investments

Wisconsin Law and Regulations. Under Wisconsin law and regulation, the Bank is authorized to make, invest in, sell, purchase, participate or otherwise deal in mortgage loans or interests in mortgage loans without geographic restriction, including loans made on the security of residential and commercial property. Wisconsin savings banks also may lend funds on a secured or unsecured basis for business, commercial or agricultural purposes, provided the total of all such loans does not exceed 20% of the savings bank’s total assets, unless the Department authorizes a greater amount. Loans are subject to certain other limitations, including percentage restrictions based on total assets.

Wisconsin savings banks may invest funds in certain types of debt and equity securities, including obligations of federal, state and local governments and agencies. Subject to prior approval of the Department, compliance with capital requirements and certain other restrictions, Wisconsin savings banks may invest in residential housing development projects. Wisconsin savings banks may also invest in service corporations or subsidiaries with the prior approval of the Department, subject to certain restrictions.

Wisconsin savings banks may make loans and extensions of credit, both direct and indirect, to one borrower in amounts up to 20% of the savings bank’s capital plus an additional 5% for loans fully secured by readily marketable collateral. In addition, and notwithstanding the 20% of capital and additional 5% of capital limitations, Wisconsin savings banks may make loans to one borrower, or a related group of borrowers, for any purpose in an amount not to

exceed $500,000, or to develop domestic residential housing units in an amount not to exceed the lesser of $30 million or 30% of the savings bank’s capital, subject to certain conditions.

Federal Law and Regulation. FDIC regulations also govern the equity investments of the Bank and, notwithstanding Wisconsin law and regulations, such regulations prohibit the Bank from making certain equity investments and generally limit the Bank’s equity investments to those that are permissible for national banks and their subsidiaries. Also, under FDIC regulations, the Bank must obtain prior FDIC approval before directly, or indirectly through a majority-owned subsidiary, engaging “as principal” in any activity that is not permissible for a national bank unless certain exceptions apply. The activity regulations provide that state banks that meet applicable minimum capital requirements would be permitted to engage in certain activities that are not permissible for national banks, including certain real estate and securities activities conducted through subsidiaries. The FDIC will not approve an activity that it determines presents a significant risk to the FDIC’s Deposit Insurance Fund. The current activities of the Bank and its subsidiaries are permissible under applicable federal regulations.

Loans to, and other transactions with, affiliates of the Bank, such as EWSB Bancorp, are restricted by the Federal Reserve Act and regulations issued by the Federal Reserve Board thereunder. See “—Transactions with Affiliates and Insiders” below.

Lending Standards

Wisconsin Law and Regulations. Wisconsin law and regulations issued by the Department impose on Wisconsin savings banks certain fairness in lending requirements and prohibit savings banks from discriminating against a loan applicant based upon the applicant’s physical condition, developmental disability, sex, marital status, race, color, creed, national origin, religion or ancestry.

Federal Law and Regulation. The federal banking agencies have adopted uniform regulations prescribing standards for extensions of credit that are secured by liens on interests in real estate or made for the purpose of financing the construction of a building or other improvements to real estate. Under the joint regulations adopted by the federal banking agencies, all insured depository institutions, such as the Bank, must adopt and maintain written policies that establish appropriate limits and standards for extensions of credit that are secured by liens or interests in real estate or are made for the purpose of financing permanent improvements to real estate. These policies must establish loan portfolio diversification standards, prudent underwriting standards (including loan-to-value limits) that are clear and measurable, loan administration procedures, and loan documentation, approval and reporting requirements. The real estate lending policies must reflect consideration of the Interagency Guidelines for Real Estate Lending Policies that have been adopted by the federal bank regulators.

The Interagency Guidelines, among other things, require a depository institution to establish internal loan-to-value limits for real estate loans that are not in excess of the following supervisory limits:

• for loans secured by raw land, 65% of the value of the collateral;

• for land development loans (i.e., loans for the purpose of improving unimproved property prior to the erection of structures), the supervisory loan-to-value limit is 75%;

• for loans for the construction of commercial, over four-family or other non-residential property, the supervisory limit is 80%;

• for loans for the construction of one- to four-family properties, the supervisory limit is 85%; and

• for loans secured by other improved property (e.g., farmland, completed commercial property and other income-producing property, including non-owner occupied, one- to four-family property), the supervisory limit is 85%.

Although no supervisory loan-to-value limit has been established for permanent mortgages on owner-occupied, one- to four-family or home equity loans, the Interagency Guidelines state that for any such loan with a loan-to-value ratio that equals or exceeds 90% at origination, an institution should require appropriate credit enhancement in the form of either mortgage insurance or readily marketable collateral.

Deposits

Wisconsin Law and Regulations. Under Wisconsin law, the Bank is permitted to establish deposit accounts and accept deposits. The Bank’s board of directors, or its designee, determines the rate and amount of interest to be paid on or credited to deposit accounts subject to FDIC limitations.

Deposit Insurance

Wisconsin Law and Regulations. Under Wisconsin law, the Bank is required to obtain and maintain insurance on its deposits from a deposit insurance corporation. The deposits of the Bank are insured up to the applicable limits by the FDIC.

Federal Law and Regulation. The Bank is a member of the Deposit Insurance Fund, which is administered by the FDIC. The Bank’s deposit accounts are insured by the FDIC, generally up to a maximum of $250,000 per separately insured depositor per account ownership category.

The FDIC imposes an assessment against all insured depository institutions. An institution’s assessment rate depends upon the perceived risk of the institution to the Deposit Insurance Fund, with less risky institutions paying lower rates. Currently, assessments for institutions of less than $10 billion of total assets are based on financial measures and supervisory ratings derived from statistical models estimating the probability of failure within three years.

The FDIC adopted a final rule in October 2022 to increase initial base deposit insurance assessment rates by two basis points beginning in the first quarterly assessment period of 2023. The FDIC may increase or decrease the range of assessments uniformly, except that no adjustment can deviate more than two basis points from the base assessment rate without notice and comment rulemaking.

The FDIC has the authority to increase insurance assessments. A significant increase in insurance premiums would have an adverse effect on the operating expenses and results of operations of the Bank. We cannot predict what deposit insurance assessment rates will be in the future.

Insurance of deposits may be terminated by the FDIC upon a finding that an institution has engaged in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. We do not know of any practice, condition or violation that might lead to termination of deposit insurance.

Capitalization

Wisconsin Law and Regulations. Wisconsin savings banks are required to maintain a minimum capital to total assets ratio of 6% and must maintain total capital necessary to ensure the continuation of insurance of deposit accounts by the FDIC. If the Department determines that the financial condition, history, management or earning prospects of a savings bank are not adequate, the Department may require a higher minimum capital level for the savings bank. If a Wisconsin savings bank’s capital ratio falls below the required level, the Department may direct the savings bank to adhere to a specific written plan established by the Department to correct the savings bank’s capital deficiency, as well as a number of other restrictions on the savings bank’s operations, including a prohibition on the payment of dividends. At December 31, 2025, the Bank’s capital to assets ratio, as calculated under Wisconsin law, was 4.9% and thus the Bank was not in compliance with this requirement. See “—Informal Agreements with Regulators.”

Federal Law and Regulation. Federal regulations require FDIC insured depository institutions to meet several minimum capital standards: a common equity Tier 1 capital to risk-based assets ratio of 4.5%, a Tier 1 capital to risk-

based assets ratio of 6.0%, a total capital to risk-based assets of 8.0%, and a 4.0% Tier 1 capital to total assets leverage ratio.

Common equity Tier 1 capital is generally defined as common stockholders’ equity and retained earnings. Tier 1 capital is generally defined as common equity Tier 1 and additional Tier 1 capital. Additional Tier 1 capital includes certain noncumulative perpetual preferred stock and related surplus and minority interests in equity accounts of consolidated subsidiaries. Total capital includes Tier 1 capital (common equity Tier 1 capital plus additional Tier 1 capital) and Tier 2 capital. Tier 2 capital is comprised of capital instruments and related surplus, meeting specified requirements, and may include cumulative preferred stock and long-term perpetual preferred stock, mandatory convertible securities, intermediate preferred stock and subordinated debt. Also included in Tier 2 capital is the allowance for credit losses limited to a maximum of 1.25% of risk-weighted assets and, for institutions that have exercised an opt-out election regarding the treatment of Accumulated Other Comprehensive Income (“AOCI”), up to 45% of net unrealized gains on available-for-sale equity securities with readily determinable fair market values. Institutions that have not exercised the AOCI opt-out have AOCI incorporated into common equity Tier 1 capital (including unrealized gains and losses on available-for-sale-securities). The Bank exercised its AOCI opt-out election. Calculation of all types of regulatory capital is subject to deductions and adjustments specified in the regulations.

In addition to establishing the minimum regulatory capital requirements, the federal regulations limit capital distributions and certain discretionary bonus payments to management if the institution does not hold a “capital conservation buffer” consisting of 2.5% of common equity Tier 1 capital to risk-weighted assets above the amount necessary to meet its minimum risk-based capital requirements.

In assessing an institution’s capital adequacy, the FDIC takes into consideration, not only these numeric factors, but qualitative factors as well, including the bank’s exposure to interest rate risk. The FDIC has the authority to establish higher capital requirements for individual institutions where deemed necessary due to a determination that an institution’s capital level is, or is likely to become, inadequate in light of particular circumstances.

The federal banking agencies have established an optional “community bank leverage ratio” of between 8% to 10% of average total consolidated assets for qualifying institutions with assets of less than $10 billion. Institutions with capital meeting the specified requirements and electing to follow the alternative framework are deemed to comply with the applicable regulatory capital requirements, including the risk-based requirements. A qualifying institution may opt in and out of the community bank leverage ratio on its quarterly call report.

The optional community bank leverage ratio has currently been established at 9%. The Bank has not opted into the community bank leverage ratio.

Safety and Soundness Standards

Each federal banking agency, including the FDIC, has adopted guidelines establishing general standards relating to internal controls, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, asset quality, earnings and compensation, fees and benefits, and information security. In general, the guidelines require, among other things, appropriate systems and practices to identify and manage the risks and exposures specified in the guidelines. The guidelines prohibit excessive compensation as an unsafe and unsound practice and describe compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, director, or principal shareholder.

Prompt Corrective Regulatory Action

Federal bank regulatory authorities are required to take “prompt corrective action” with respect to institutions that do not meet minimum capital requirements. For these purposes, the federal statute and regulations establish five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. Under the statute and regulations, a bank is deemed to be (i) “well capitalized” if it has total risk-based capital of 10.0% or more, Tier 1 risk-based capital ratio of 8.0% or more, Tier 1 leverage capital ratio of 5.0% or more and a common equity Tier 1 capital ratio of 6.5% or more, and is not subject to any written capital order or directive;

(ii) “adequately capitalized” if it has a total risk-based capital ratio of 8.0% or more, a Tier 1 risk-based capital ratio of 6.0% or more, a Tier 1 leverage capital ratio of 4.0% or more and a common equity Tier 1 capital ratio of 4.5% or more, and does not meet the definition of “well capitalized;” (iii) “undercapitalized” if it has a total risk-based capital ratio that is less than 8.0%, a Tier 1 risk-based capital ratio that is less than 6.0%, a Tier 1 leverage capital ratio that is less than 4.0% or a common equity Tier 1 capital ratio of less than 4.5%; (iv) “significantly undercapitalized” if it has a total risk-based capital ratio that is less than 6.0%, a Tier 1 risk-based capital ratio that is less than 4.0% , a Tier 1 leverage capital ratio that is less than 3.0%, or a common equity Tier 1 capital ratio of less than 3.0%; and (v) “critically undercapitalized” if it has a ratio of tangible equity to total assets that is equal to or less than 2.0%. A qualifying institution whose Tier 1 capital equals or exceeds the specified community bank leverage ratio and opts into that framework will be considered well capitalized for prompt corrective action purposes.

Federal law and regulations also specify circumstances under which a federal banking agency may reclassify a well-capitalized institution as adequately capitalized and may require an institution classified as less than well capitalized to comply with supervisory actions as if it were in the next lower category (except that the FDIC may not reclassify a significantly undercapitalized institution as critically undercapitalized).

The FDIC may order savings banks that have insufficient capital to take corrective actions. For example, a savings bank that is categorized as “undercapitalized” is subject to growth limitations and is required to submit a capital restoration plan, and a holding company that controls such a savings bank is required to guarantee that the savings bank complies with the capital restoration plan. A “significantly undercapitalized” savings bank may be subject to additional restrictions. Savings banks deemed by the FDIC to be “critically undercapitalized” are generally subject to the appointment of a receiver or conservator within 270 days after it is determined to be critically undercapitalized, subject to a narrow exception.

At December 31, 2025, the Bank’s capital levels exceeded the levels required to be technically considered “well-capitalized” with a common equity Tier 1 capital ratio of 10.8%, Tier 1 leverage ratio of 6.1%, a Tier 1 risk-based capital ratio of 10.8% and a total risk-based capital ratio of 11.6%.

Dividends

Wisconsin Law and Regulations. Under Wisconsin law and applicable regulations, a Wisconsin savings bank that meets its regulatory capital requirements may declare dividends on capital stock based upon net profits, provided that its paid-in surplus equals its capital stock. In addition, prior Department approval is required before dividends exceeding 50% of net profits for any calendar year may be declared and before a stock dividend may be declared out of retained earnings. Under Department regulations, a Wisconsin savings bank which has converted from mutual to stock form also is prohibited from paying a dividend on its capital stock if the payment causes the regulatory capital of the savings bank to fall below the amount required for its liquidation account.

Federal Law and Regulation. The FDIC has the authority to prohibit the Bank from paying dividends if, in its opinion, the payment of dividends would constitute an unsafe or unsound practice in light of the financial condition of the Bank. Institutions may not pay dividends if they would be “undercapitalized” following payment of the dividend within the meaning of the prompt corrective action regulations.

Liquidity and Reserves

Wisconsin Law and Regulations. Under Department regulations, all Wisconsin savings banks are required to maintain a certain amount of their assets as liquid assets, consisting of cash and certain types of investments. The exact amount of assets a savings bank is required to maintain as liquid assets is set by the Department, but generally ranges from 4% to 15% of the savings bank’s average daily balance of net withdrawable accounts plus short-term borrowings (the “Required Liquidity Ratio”). At December 31, 2025, the Bank was in compliance with this requirement. In addition, 50% of the liquid assets maintained by a Wisconsin savings bank must consist of “primary liquid assets,” which are defined to include securities issued by the United States Government, United States Government agencies, or the state of Wisconsin or a subdivision thereof, and cash. At December 31, 2025, the Bank was in compliance with this requirement.

Federal Law and Regulation. Under federal law and regulations, the Bank is required to maintain sufficient liquidity to ensure safe and sound banking practices. Regulation D, promulgated by the Federal Reserve Board, imposes reserve requirements on all depository institutions, including the Bank, which maintain transaction accounts or non-personal time deposits. Checking accounts, NOW accounts, Super NOW checking accounts, and certain other types of accounts that permit payments or transfers to third parties fall within the definition of transaction accounts and are subject to Regulation D reserve requirements, as are any nonpersonal time deposits (including certain money market deposit accounts) at a savings institution. However, effective March 26, 2020, the Federal Reserve Board reduced reserve requirement ratios to zero, thereby effectively eliminating the requirements. The Federal Reserve Board took that action due to a change in its approach to monetary policy; it has indicated that it has no plans to re-impose reserve requirements but could in the future if conditions warrant.

Transactions with Affiliates and Insiders

Wisconsin Law and Regulations. Under Wisconsin law, a savings bank may not make a loan to a person owning 10% or more of its stock, an affiliated person (including a director, officer, the spouse of either and a member of the immediate family of such person who is living in the same residence), agent, or attorney of the savings bank, either individually or as an agent or partner of another, except as under the rules of the Department and regulations of the FDIC. In addition, unless the prior approval of the Department is obtained, a savings bank may not purchase, lease or acquire a site for an office building or an interest in real estate from an affiliated person, including a shareholder owning more than 10% of its capital stock, or from any firm, corporation, entity or family in which an affiliated person or 10% shareholder has a direct or indirect interest.

Federal Law and Regulation. Sections 23A and 23B of the Federal Reserve Act govern transactions between member banks and their “affiliates”. The Federal Reserve Board has adopted Regulation W, which comprehensively implements and interprets Sections 23A and 23B, in part by codifying prior Federal Reserve Board interpretations under Sections 23A and 23B. Section 18(j) of the Federal Deposit Insurance Act makes Sections 23A and 23B of the Federal Reserve Act applicable to FDIC-supervised savings banks, such as the Bank, and its affiliates, including EWSB Bancorp.

An affiliate of a savings bank is any company or entity that controls, is controlled by or is under common control with the savings bank. In general, a subsidiary of a savings bank that is not also a depository institution or a “financial subsidiary” under federal law is not treated as an affiliate of the savings bank for the purposes of Sections 23A and 23B and Regulation W; however, the FDIC has the discretion to treat subsidiaries of a savings bank as affiliates on a case-by-case basis. Section 23A and Regulation W limit the extent to which a savings bank or its subsidiaries may engage in “covered transactions” with any one affiliate to an amount equal to 10% of such savings bank’s capital stock and surplus, and limit all such transactions with all affiliates to an amount equal to 20% of such capital stock and surplus. The term “covered transaction” includes the making of loans, purchase of assets, issuance of guarantees and other similar types of transactions. Further, most loans and other extensions of credit by a savings bank to any of its affiliates must be secured by collateral in amounts ranging from 100% to 130% of the loan amounts, depending on the type of collateral. In addition, under Section 23B and Regulation W, transactions, including covered transactions between a savings bank and an affiliate must generally be on terms and under circumstances that are substantially the same, or at least as favorable, to the savings bank as those prevailing at the time for comparable transactions with or involving a non-affiliate, and be consistent with safe and sound banking practices.

A savings bank’s loans to its and its affiliates’, executive officers, directors, any owner of more than 10% of its stock (each, an insider) and any of certain entities affiliated with any such person (an insider’s related interest) are subject to the conditions and limitations imposed by Section 22(h) of the Federal Reserve Act and the Federal Reserve Board’s Regulation O thereunder, as made applicable to the Bank by Section 18(j) of the Federal Deposit Insurance Act and FDIC regulation.. Under these restrictions, the aggregate amount of the loans to any insider and the insider’s related interests may not exceed the loans to-one-borrower limit applicable to national banks, (which is generally 15% of unimpaired capital and unimpaired surplus). Aggregate loans by a savings bank to its and its affiliates’ insiders and insiders’ related interests in the aggregate may not exceed the savings bank’s unimpaired capital and unimpaired surplus. Regulation O also requires that any proposed loan to an insider or a related interest of that insider be approved in advance by a majority of the board of directors of the savings bank, with any interested director not participating in the

voting, if such loan, when aggregated with any existing loans to that insider and the insider’s related interests, would exceed either $500,000 or the greater of $25,000 or 5% of the savings bank’s unimpaired capital and surplus. Generally, loans to a savings bank or its affiliates’ insiders and their related interests must be made on substantially the same terms as, and follow credit underwriting procedures that are no less stringent than those that are prevailing at the time for comparable transactions with non-affiliated persons and they must not present more than a normal risk of repayment or present other unfavorable features. With certain exceptions, loans to an executive officer, other than loans for the education of the officer’s children and certain loans secured by the officer’s primary residence, may not exceed the greater of $25,000 or 2.5% of the savings bank’s unimpaired capital and unimpaired surplus, but in no event may such loan be more than $100,000.

An exception to certain requirements under Regulation O is made for extensions of credit made pursuant to a benefit or compensation plan of a bank that is widely available to employees of the savings bank and that does not give any preference to insiders of the bank over other employees of the bank.

Transactions between Bank Customers and Affiliates

Wisconsin savings banks, such as the Bank, are subject to prohibitions on certain tying arrangements. Subject to certain exceptions, a savings bank is prohibited from extending credit to or offering any other service to a customer, or fixing or varying the consideration for such extension of credit or service, on the condition that such customer obtain some additional service from the institution or certain of its affiliates or not obtain services of a competitor of the institution.

Examinations and Assessments

The Bank is required to file periodic reports with and is subject to periodic examinations by the Department and the FDIC. The Bank is required to pay examination fees and annual assessments to fund its supervision. Federal regulations require annual on-site examinations for all depository institutions except certain well-capitalized and highly rated institutions with assets of less than $3 billion that are examined every 18 months.

Customer Privacy

Under Wisconsin and federal law and regulations, savings banks, such as the Bank, are required to develop and maintain privacy policies relating to information on its customers, restrict access to and establish procedures to protect customer data. Applicable privacy regulations further restrict the sharing of nonpublic customer data with non-affiliated parties if the customer requests.

Cybersecurity

The federal banking agencies have adopted regulations providing for notification requirements for banking organizations and their service providers for significant cybersecurity incidents. Specifically, the regulations require a banking organization to notify its primary federal regulator as soon as possible, and no later than 36 hours after, the banking organization determines that a “computer-security incident” rising to the level of a “notification incident” has occurred. Notification is required for incidents that have materially affected or are reasonably likely to materially affect the viability of a banking organization’s operations, its ability to deliver banking products and services, or the stability of the financial sector. Service providers are required under the regulations to notify affected banking organization customers as soon as possible when the provider determines that it has experienced a computer-security incident that has materially affected or is reasonably likely to materially affect the banking organization’s customers for four or more hours.

Community Reinvestment Act

Under the CRA, the Bank has a continuing and affirmative obligation consistent with its safe and sound operation to help meet the credit needs of its entire community, including low- and moderate-income neighborhoods. The CRA does not establish specific lending requirements or programs for financial institutions nor does it limit an

institution’s discretion to develop the types of products and services that it believes are best suited to its particular community, consistent with the CRA. The CRA requires the FDIC, in connection with its examination of the Bank, to assess our record of meeting the credit needs of its community and to take such record into account in its evaluation of certain applications by the Bank, including applications to establish branches and acquire other financial institutions. The CRA currently requires the FDIC to provide a written evaluation of an institution’s CRA performance utilizing a four-tiered descriptive rating system. The Bank’s most recent FDIC CRA rating in December 2020 was “Satisfactory.” On October 24, 2023, the FDIC and other federal bank regulatory agencies issued a final rule to strengthen and modernize the CRA regulations. The changes were designed to encourage banks to expand access to credit, investment and banking services in low- and moderate-income communities, adapt to changes in the banking industry including mobile and internet banking, provide greater clarity and consistency in the application of the CRA regulations and tailor CRA evaluations and data collection to bank size and type. Under the final rule, banks with assets of less than $600 million as of December 31 in both of the prior two calendar years will be a “small bank.” The agencies will evaluate small banks under the Small Bank Lending Test or, at the bank’s option, the Retail Lending Test. Under the new regulations, the applicability date for the majority of the provisions is January 1, 2026, and additional requirements under the new regulation will be applicable on January 1, 2027. On March 29, 2024, a federal court in the Northern District of Texas issued a preliminary injunction of the new CRA regulations, enjoining the federal banking agencies from enforcing the regulations against the plaintiff bank industry trade groups, and extending the regulations’ implementation dates day-for-day for each day the injunction is in place.

Federal Home Loan Bank System

The Federal Home Loan Bank System, consisting of 11 Federal Home Loan Banks, is under the jurisdiction of the Federal Housing Finance Agency. The designated duties of the Federal Housing Finance Agency are to supervise the Federal Home Loan Banks; ensure that the Federal Home Loan Banks carry out their housing finance mission; ensure that the Federal Home Loan Banks remain adequately capitalized and able to raise funds in the capital markets; and ensure that the Federal Home Loan Banks operate in a safe and sound manner.

The Bank, as a member of the FHLB, is required to acquire and hold shares of capital stock in the FHLB in specified amounts. The Bank is in compliance with this requirement with an investment in FHLB stock of $2.8 million at December 31, 2025.

Among other benefits, the Federal Home Loan Banks provide a central credit facility primarily for member institutions. It is funded primarily from proceeds derived from the sale of consolidated obligations of the Federal Home Loan Bank System. It makes advances to members in accordance with policies and procedures established by the Federal Housing Finance Agency and the board of directors of the FHLB. At December 31, 2025, the Bank had $38.4 million in advances from the FHLB.

USA PATRIOT Act

The USA PATRIOT Act gives the federal government powers to address terrorist threats through enhanced domestic security measures, expanded surveillance powers, increased information sharing and broadened anti-money laundering requirements. The USA PATRIOT Act also requires the federal banking agencies to take into consideration the effectiveness of controls designed to combat money laundering activities in determining whether to approve a merger or other acquisition application of a member institution. Accordingly, if the Bank engages in a merger or other acquisition, the Bank’s controls designed to combat money laundering would be considered as part of the application process. The Bank has established policies, procedures and systems designed to comply with the Bank Secrecy Act, USA PATRIOT Act, and their implementing regulations related to anti-money laundering and countering the financing of terrorism.

Holding Company Regulation

General. EWSB Bancorp is a bank holding company within the meaning of the BHCA. As such, EWSB Bancorp is registered with the Federal Reserve Board and is subject to the regulation, examination, supervision and reporting requirements applicable to bank holding companies. In addition, the Federal Reserve Board has enforcement authority over EWSB Bancorp and its non-bank subsidiaries. Among other things, this authority permits the Federal Reserve Board to restrict or prohibit activities that are determined to be a serious risk to the subsidiary bank. Acquisitions of additional banks or savings banks by a bank holding company generally require the prior approval of the Federal Reserve Board.

Permissible Activities. A bank holding company is generally prohibited from engaging in non-banking activities, or acquiring direct or indirect control of more than 5% of the voting securities of any company engaged in non-banking activities. One of the principal exceptions to this prohibition is for activities found by the Federal Reserve Board to be so closely related to banking or managing or controlling banks as to be a proper incident thereto. Some of the principal activities that the Federal Reserve Board has determined by regulation to be so closely related to banking are: (i) making or servicing loans; (ii) performing certain data processing services; (iii) providing discount brokerage services; (iv) acting as fiduciary, investment or financial advisor; (v) leasing personal or real property; (vi) making investments in corporations or projects designed primarily to promote community welfare; and (vii) acquiring a savings and loan association whose direct and indirect activities are limited to those permitted for bank holding companies.

The Gramm-Leach-Bliley Act of 1999 authorized a bank holding company that meets specified conditions, including being “well capitalized” and “well managed,” to opt to become a “financial holding company” and thereby engage in a broader array of financial activities than previously permitted. Such activities can include insurance underwriting and investment banking.

Capital. Bank holding companies are subject to consolidated regulatory capital requirements, which have historically been similar to, though less stringent than, those of the FDIC for the Bank. Federal legislation enacted in 2010, however, required the Federal Reserve Board to promulgate consolidated capital requirements for depository institution holding companies that are no less stringent, both quantitatively and in terms of components of capital, than those applicable to institutions themselves. A framework of consolidated regulatory capital requirements identical to that applicable to the subsidiary banks applies to bank holding companies. However, the Federal Reserve Board has provided a “Small Bank Holding Company” exception to its consolidated capital requirements, and 2018 legislation, and the related regulations, increased the threshold for the exception to $3.0 billion. As a result, the Federal Reserve Board’s consolidated holding company regulatory capital requirements do not presently apply to EWSB Bancorp.

Source of Strength. The Federal Reserve Board has issued regulations requiring that all bank holding companies serve as a source of strength to their subsidiary depository institutions by providing financial, managerial and other support in times of an institution’s distress.

Dividends and Stock Repurchases. The Federal Reserve Board has issued a policy statement regarding the payment of dividends by bank holding companies. In general, the policy provides that dividends should be paid only out of current earnings and only if the prospective rate of earnings retention by the holding company appears consistent with the organization’s capital needs, asset quality and overall supervisory financial condition. Separate regulatory guidance provides for prior consultation with Federal Reserve Bank staff concerning dividends in certain circumstances such as when the holding company’s net income for the past four quarters, net of dividends previously paid over that period, is insufficient to fully fund the dividend, the proposed dividend is not covered by earnings for the period for which the dividend is being paid or the company’s overall rate or earnings retention is inconsistent with the company’s capital needs and overall financial condition. The ability of a bank holding company to pay dividends may be restricted if a subsidiary savings bank becomes undercapitalized.

Federal Reserve Board regulatory guidance also states that a bank holding company should consult with Federal Reserve Bank supervisory staff prior to redeeming or repurchasing common stock or perpetual preferred stock if the bank holding company is experiencing financial weaknesses or the repurchase or redemption would result in a net

reduction, at the end of a quarter, in the amount of such equity instruments outstanding compared with the beginning of the quarter in which the redemption or repurchase occurred.

There is a separate requirement that a bank holding company give the Federal Reserve Board prior written notice of any purchase or redemption of then outstanding equity securities if the gross consideration for the purchase or redemption, when combined with the net consideration paid for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of the company’s consolidated net worth. The Federal Reserve Board may disapprove such a purchase or redemption if it determines that the proposal would constitute an unsafe and unsound practice, or would violate any law, regulation, Federal Reserve Board order or directive, or any condition imposed by, or written agreement with, the Federal Reserve Board. There is an exception to this approval requirement for well-capitalized bank holding companies that meet certain other conditions.

These regulatory policies may affect the ability of EWSB Bancorp to pay dividends, repurchase shares of common stock or otherwise engage in capital distributions.

Change in Control Regulations

Under the Change in Bank Control Act, no person or group of persons may acquire “control” of a bank holding company unless the Federal Reserve Board has been given 60 days’ prior written notice and has not issued a notice disapproving the proposed acquisition, taking into consideration certain factors, including the financial and managerial resources of the acquirer and the competitive effects of the acquisition. Control, as defined by the Change in Bank Control Act and its implementing regulations, means the power, directly or indirectly, to direct the management or policies of an institution or ownership, control of or holding with the power to vote 25% or more of any class of voting stock. There is a rebuttal presumption of control upon the acquisition of 10% or more of a class of voting stock if (i) the holding company involved has its shares registered under Section 12 of the Exchange Act, or (ii) if no other person will own, control or hold the power to vote a greater percentage of that class of voting stock after the acquisition.

In addition, the BHCA prohibits any company from acquiring control of a bank or bank holding company without first having obtained the approval of the Federal Reserve Board. Among other circumstances, under the BHCA, a company has control of a bank or bank holding company if the company owns, controls or holds with power to vote 25% or more of a class of voting securities of the bank or bank holding company, controls in any manner the election of a majority of directors or trustees of the bank or bank holding company, or the Federal Reserve Board has determined, after notice and opportunity for hearing, that the company has the power to exercise a controlling influence over the management or policies of the bank or bank holding company. The Federal Reserve Board has established circumstances under which an entity could be determined to acquire control of a bank holding company for purposes of the BHCA, including the acquisition of control of 5% or more of a class of voting securities of a bank holding company, together with other factors enumerated by the Federal Reserve Board.

Federal Securities Laws

The common stock of EWSB Bancorp is registered with the SEC. EWSB Bancorp is subject to the information, proxy solicitation, insider trading restrictions and other requirements under the Exchange Act.

The registration, under the Securities Act of 1933, as amended (the “Securities Act”), of shares of common stock issued in the initial public offering of EWSB Bancorp does not cover the subsequent resale of those shares. Shares of common stock purchased by persons who are not affiliates of EWSB Bancorp may be resold without registration. Shares purchased by an affiliate of EWSB Bancorp are subject to the resale restrictions of Rule 144 under the Securities Act. If EWSB Bancorp meets the current public information requirements of Rule 144 under the Securities Act, each affiliate of EWSB Bancorp that complies with the other conditions of Rule 144, including those that require the affiliate’s sale to be aggregated with those of other persons, would be able to sell in the public market, without registration, a number of shares not to exceed, in any three-month period, the greater of 1% of the outstanding shares of EWSB Bancorp, or the average weekly volume of trading in the shares during the preceding four calendar weeks.

Sarbanes-Oxley Act of 2002

The Sarbanes-Oxley Act of 2002 is intended to improve corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly traded companies and to protect investors by improving the accuracy and reliability of corporate disclosures pursuant to the securities laws. EWSB Bancorp has adopted policies, procedures and systems designed to comply with this Act and its implementing regulations, and will review and document such policies, procedures and systems to ensure continued compliance with this Act and its implementing regulations.

Emerging Growth Company Status

EWSB Bancorp is an emerging growth company. For as long as it continues to be an emerging growth company, it may choose to take advantage of exemptions from various reporting requirements applicable to public companies. These exemptions include, but are not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As an emerging growth company, EWSB Bancorp is not subject to Section 404(b) of the Sarbanes-Oxley Act of 2002, which would require that our independent auditors audit our internal control over financial reporting. We have also elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Such an election is irrevocable during the period a company is an emerging growth company.

EWSB Bancorp will cease to be an emerging growth company upon the earliest of: (i) the end of the fiscal year following the fifth anniversary of the completion of the conversion and offering; (ii) the first fiscal year after our annual gross revenues are $1.235 billion (adjusted for inflation) or more; (iii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities; or (iv) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700 million at the end of the second quarter of that fiscal year. We expect to lose our status as an emerging growth company effective December 31, 2029, which is the end of the fifth year after the completion date of the conversion and offering.

Informal Agreements with Regulators

In July 2023, the Bank entered into a confidential MOU with the FDIC and the Department, the Bank’s primary banking regulators. While the contents of the MOU are confidential under Department and FDIC regulations, certain provisions, with the authorization of the Department and the FDIC, are summarized below.

Pursuant to the MOU, the Bank has agreed to address certain practices and conditions identified during regulatory examinations, including, among other things, the level and management of its capital, earnings and liquidity as well as its investment and information technology management. The Bank has also agreed to enhancements to board oversight, asset/liability management, and risk management. Under the MOU, the Bank has agreed to certain provisions, including:

• Develop and adhere to a comprehensive strategic plan.

• Improve the Bank’s funds management practices, formulate and adopt a plan for improving the Bank’s liquidity position.

• Develop a plan to reduce and better manage its interest rate risk exposure.

• Increase the Bank’s Tier 1 capital and total risk-based capital ratios to levels above those required by federal regulatory capital regulations and maintain a net worth ratio (as defined under Wisconsin law) of at least 6%.

• While the MOU is in effect, the Bank will not declare or pay any dividends without prior written consent of the FDIC and the Department.

• Improve oversight of the Bank’s information technology audit program and implement a vendor management program.

The Bank has developed and adopted strategic and other plans and has adopted and submitted to the FDIC and Department a capital plan in accordance with the MOU and will operate within the parameters of such plans. Any material deviations from such plans will require prior regulatory approval. The Bank has also engaged an auditor to implement an audit program for information technology and engaged service providers to assist in testing operating contingencies. With regard to interest rate risk, the Bank has revamped its interest rate risk management processes and procedures with enhanced education and training.

Failure to address the corrective measures identified in the MOU could result in further enforcement actions by the FDIC or the Department. The Bank has expended significant resources in connection with the MOU, and our continued efforts to comply with the MOU may restrict our operations or result in the continued expenditure of significant resources, which could have adverse effects on our operations and financial condition.

TAXATION

Federal Taxation

General. EWSB Bancorp and the Bank are subject to federal income taxation in the same general manner as other corporations, with some exceptions discussed below. The following discussion of federal taxation is intended only to summarize material federal income tax matters and is not a comprehensive description of the tax rules applicable to EWSB Bancorp and the Bank.

Method of Accounting. For federal income tax purposes, the Bank currently reports its income and expenses on the accrual method of accounting and uses a tax year ending December 31 for filing its federal income tax returns.

Net Operating Loss Carryovers. Generally, a financial institution may carry net operating losses forward indefinitely. At December 31, 2025, the Bank has a net operating loss carry-forward of $11.4 million.

Capital Loss Carryovers. A corporation cannot recognize capital losses in excess of capital gains generated. Generally, a financial institution may carry back capital losses to the preceding three taxable years and forward to the succeeding five taxable years. Any capital loss carryback or carryover is treated as a short-term capital loss for the year to which it is carried. As such, it is grouped with any other capital losses for the year to which it is carried and is used to offset any capital gains. Any undeducted loss remaining after the five-year carryover period is not deductible. At December 31, 2025, the Bank had no capital loss carryovers.

Corporate Dividends. EWSB Bancorp may generally exclude from its income 100% of dividends received from the Bank as a member of the same affiliated group of corporations.

Audit of Tax Returns. Neither the Bank’s federal income tax returns, nor the consolidated returns of the EWSB Bancorp’s have been audited in the most recent five-year period.

State Taxation

As a Maryland business corporation, EWSB Bancorp is required to file an annual report with and pay franchise taxes to the state of Maryland.

EWSB Bancorp is subject to the Wisconsin corporate franchise (income) tax. The State of Wisconsin imposes a corporate franchise tax of 7.9% on the combined taxable income of the members of a consolidated income tax group.

In general, Wisconsin net business losses may be carried forward to the succeeding 20 taxable years. However, losses originated in taxable years beginning before 2009 may be carried forward to tax years beginning before 2042. At December 31, 2025, the Bank had approximately $9.0 million of Wisconsin net business loss carry-forwards.

Expense and Tax Allocation

The Bank entered into an agreement with EWSB Bancorp to provide it with certain administrative support services for compensation not less than the fair market value of the services provided. In addition, the Bank and EWSB Bancorp entered into an agreement to establish a method for allocating and for reimbursing the payment of their consolidated tax liability.
